Yelu Zhen said: "This seat is actually just here to take a look at the situation of the mount, there are still many things to deal with, if the mount is in the palace, I will come back at night and take you away directly." ”

"Unreasonable...... Zong Xin said depressedly: "Forget it, let's eat first, Tianya, how many layers have you practiced in the Nine Yang Burning Heaven Technique?"

"Master, I haven't learned the first yang yet, so I can't help but have a poor martial arts foundation. ”

"It's okay, it's okay, practice slowly, anyway, I've learned it as a teacher. You have to practice hard, and to be a teacher is to suffer the loss of too poor martial arts, so you can't repeat the mistakes of the past, you know?"

Tianya nodded and said, "That's right, Master, if you practiced martial arts a few years earlier, you would definitely be more powerful than now." What did you do before?"

"Reading and writing is also very hard, but as a teacher, I also realized a truth, in fact, you don't need to read and write, as long as your martial arts are good enough, no one will dare to mess with you. When you grow up, your martial arts will be better than that of your teacher, and whoever dares to provoke you will kill his whole family, and he will destroy the whole country if he is really angry. ”

"Well, the disciple will work hard. ”

A large group of people watched these two masters and apprentices talk nonsense, and all of them didn't understand why Zongxin wanted to teach his disciples like this. In fact, although Zongxin's martial arts are good, his martial arts are worthless compared to other skills...... Zong recognized his talent and military attainments, Yelu Zhen would rather exchange all his martial arts in exchange, but Zong Xin was more concerned about the level of martial arts, is there something wrong with this person?

"Little brother, you feel weird, don't you?"

"Nonsense, did Zong Xin say this on purpose?" Ye Luzhen said depressedly: "He just doesn't want others to know how he teaches his disciples, so he deliberately said that martial arts are more important." I think Zongxin spent most of his time teaching the art of war and statecraft. This kid is Guo Wei's son, if he learns Zongxin's skills, will our Khitan still have a way to live?"

Yeluhong said depressedly: "It's no wonder that you don't communicate much with Zongxin. You don't know the special internal skills of Zongxin...... They can speak when they practice internal strength, and their thoughts are very clear, more clearly than usual. Therefore, Zongxin spent most of his time teaching Tianya exercises, and lecturing to him while practicing. Little brother, if you have time to listen to Master Zongxin's lectures, I can guarantee that you will be willing to drive for him for the rest of your life. ”

"What's the rush?"

Yeluhong said: "Zongxin's carriage is larger than ordinary people, and they can sit cross-legged in the carriage to practice. While practicing, Zongxin gave a lecture to Tianya, and I offered to catch a car for Zongxin. Because when I was in the car, I could eavesdrop on the lectures of the sect...... What I want to do most now is to drive a car for Zongxin for the rest of my life. ”

Speaking of this, Yelu Zhen also became a little interested, and then asked, "What did Zongxin say?"

"He said whatever he wanted to say, and he said all the things we didn't know, but I now know what was going on in Zongxin's salt island. If I can, when this is done, I will also go to the coast to make salt. There is no need to burn it, just let the water actively evaporate to turn into salt. ”

"I've always been very curious about this matter, how did Zongxin manage it? ”

"It's a natural phenomenon called evaporation. It's like a bowl of water that is placed there, and after a while the bowl of water will become less and less, and finally disappear completely, and the process is evaporation. "Evaporation is the process by which water changes from a liquid to a gas, and it can occur at any temperature. In other words, even if it is frozen into ice, the ice will evaporate. The speed of evaporation varies according to natural conditions, the flow of air, the temperature of the air, and the humidity around it will affect the speed of evaporation, but the most important is the temperature. ”

Yelu is really perceptive, and after thinking about it for a while, he immediately understood that he had not paid attention to this kind of thing before, but Zongxin actually noticed it, and summed it up, and it was really a generation of masters.

Jeluhon continued: "My method of boiling can make the water boil, that is, boiling. Boiling is actually a violent evaporation phenomenon. Water is a liquid, and the process of changing from liquid to gas increases its volume, so many blisters will emerge when boiling. But even if you don't boil it, the sea water will still evaporate, so you only need to introduce some seawater into a pool and expose it to the sun's high temperature, and the sea water will evaporate very quickly, as long as the pool is big enough and submersible enough, the water will soon disappear, and all that remains is salt. ”

"Oh~~ I understand when you say that. Jeremiah said, "If a bowl of water is placed under the sun, it will gradually become less and less, and finally it will disappear." This is true of ordinary water, and so is the case with seawater. So there is no need to cook it with fire at all, we can also make the water in it disappear so that we can get salt. ”

Yeluhong said: "Yes, that's the simple truth. I couldn't figure it out before, but after being brought up by Master Zongxin, it was easy to understand. The method of boiling seawater with fire is too stupid, time-consuming, labor-intensive, and it also requires constant cutting down of surrounding trees, which will soon be cut down. You can only boil one pot of water at a time, which is too wasteful, isn't it? It's a good way to use the sun, it doesn't take many people to run it, and it's a lot of money, it's a good business. ”

Yeluzhen nodded and said, "It's really good, if you don't say it, I'm afraid I won't be able to figure out how Zongxin made salt from the sea for the rest of my life." It turned out to be such a simple truth. This is what you eavesdropped on for Zongxin's car?"

"No, not overheard, but openly heard. Sometimes I would ask questions, and Master Zongxin would answer my questions, and he didn't keep these things secret, but was happy that someone would learn them. ”

Jeruzhen took a deep breath and felt a little scary. Because this knowledge is valuable, people who have this knowledge generally do not share it. There are only two possibilities for Zongxin's behavior, one is that this knowledge is worthless to Zongxin, and he has more and more advanced knowledge.

If that's the case, it's terrible, because this knowledge that is worthless to Zongxin can make him rich, almost the entire Central Plains is staring at his salt island industry, Da Zhou Guo Wei and Tang Li Jing both accept his benefits, and are even willing to send people to help him garrison Yan Island, is this knowledge really worthless? Absolutely not.

In this way, there is only the second possibility, Zongxin is a true enlightened monk, and he is willing to share his knowledge with others. As long as others are willing to learn, he is willing to teach.

Whatever the case may be, Jeluzhen was once again sure that Zongxin was an extremely terrible person, a person who could never afford to offend......

Yelu Zhen was curious: "What else did you learn from Master Zongxin?"

"That's a lot, and a lot of things are useful, I'll tell you slowly......" Yeluhong actually wanted to tell his younger brother about the knowledge he had learned openly and honestly, but his younger brother was too busy recently and might not have so much time. I only took this opportunity to tell my little brother everything I wanted to say, and sure enough, Yelu was speechless and dumbfounded.

After listening to Yeluhong's description, Yeluzhen had an impulse to catch the car for Zongxin...... Because this knowledge is so precious, it is no wonder that Zongxin was able to become famous all over the world at such a young age. The knowledge he possesses is by no means comparable to that of ordinary people, and even those so-called scholars may not have heard of the theories and knowledge just now.

When Zongxin was eating, the two brothers kept talking, and when they were finished eating, they were still talking, and after Zongxin slept for a while, the two brothers were still discussing the knowledge that Yeluhong had overheard. Because he is very interested in agriculture, he heard from Yeluhong that in fact, sorghum is better than wheat in the Khitan territory, and the taste of wheat is naturally better than sorghum, but the general public will also like sorghum, because it is a high-quality sorghum, and the Khitan economy will prosper again.

This point has also been affirmed by Yeluzhen, winter wheat and spring ploughing were proposed by Zongxin, and these four words greatly increased the grain production of the Khitan. However, the next problem also comes, although wheat is delicious and the yield is also very good, there are also some shortcomings, that is, wheat needs to be carefully cared for, and a nation cannot eat only one kind of food, it needs to have some different changes.

Sorghum is a very good choice, and it came from the mouth of Master Zongxin, which also makes Yeluzhen and Yeluhong feel that this matter is feasible. After all, the spring wheat of the Khitan has been harvested, and the wheat grown in the Khitan feels fragrant and delicious to everyone, which also greatly reduces the food burden of the Khitan. For a nomadic people, they can let a large part of the people slowly transform into farmers, farmers are the most stable profession, as long as there are no natural disasters, they can live very satisfied.

Jeruzhen did not look down on his people, but his nomadic life was far less stable than farming. In order for society to develop, it is necessary to make changes, although the process of change will be a little uncomfortable, but the final result is to make everyone's life easy and comfortable.

In fact, Yeluhong also said several problems that Yeluzhen hadn't paid attention to before, and Yeluzhen really felt that Zongxin was amazing. This is just something that Yeluhong has learned in the short time he has been in contact with Zongxin, Tianya has been Zongxin's apprentice for two years, how much has he learned? As the future heir of the Great Zhou, wouldn't it be terrible if the Khitan had such an opponent?

Soon, it was dark. Although Yeluzhen wanted to talk a little more, he was helpless to do what he had to do.

Yeluzhen found Zongxin, and at this time Zongxin was enjoying his gentle hometown. Lying on a chair, three beautiful girls waiting, one rubbing his shoulders, one hammering his legs, and the other sitting next to him to feed him fruits, this day did not look like a monk at all......
